m4p™ 316l
m4p™ CH100-Fe
m4p™ CH100-Fe is used for mechanically demanding applications in general mechanical engineering, automotive engineering and safety engineering. The special alloy was developed and optimized to meet the requirements of additive manufacturing, so that crack-free and low-porosity components can be manufactured reproducibly within a relatively wide range of parameters. Processing is carried out at temperatures of <200°C. Characteristic are the exceptionally good ductility values with simultaneously high strength and hardness properties.
Notched bar impact energy of 100J is measured in the quenched and tempered state, which makes the use of m4p™ CH100-Fe for critical and safety-relevant components in gear construction or fastening technology
m4p™ CXplus
m4p™ CXplus is a high-performance powder that was developed to meet the special needs of additive manufacturing. It combines the excellent processing properties of maraging steel (like m4p™ Fe-2709) with the corrosion resistance of stainless steel material (like m4p™ 316l). The user is thus provided with a unique combination of material properties in just one powder quality, comprising very good powder bed processability, a high level of corrosion resistance with adjustable high hardness values of up to
54HRC (52HRC+2HRC maximum hardness).
The setting of the described advantageous properties of the m4p™ CXplus takes place already in the powder manufacturing process, which is characterized by the fine tuning of the alloying elements and the metallurgical processing of the melted mass under vacuum. The hardness values can be set in a targeted manner by means of a heat treatment following the additive manufacturing.
m4p™ Fe-545
m4p™ Fe-545 is a low-alloy metal powder developed for use in the Laser Powder Bed Fusion (L-PBF) process. It is classified as a fine-grained steel and is comparable to the material S355 / 1.0545. The material boasts a fine-grained microstructure and high strain capability with yield strengths greater than 350 MPa, which are particularly notable. Unlike fine-grain structural steels that require thermomechanical pretreatment to obtain their property profile, m4p™ Fe-545 does not require such treatment. Additively manufactured parts can be used in their as-built condition without the need for costly post-treatment.
This advantage is achieved through an alloy-effective material adaptation, eliminating the need for post-treatment and counteracting the influence of component volume. Due to the carbon content, larger component volumes with fine-grain structural steels are typically critical, making additive manufacturing more challenging. This issue was addressed and advantageously reduced in the development of m4p™ Fe-545. The metallurgical intervention ensures that there are minimal deviations from the property profile of fine-grain structural steels, except for a reduction in tensile stress in the as-built state.
m4p™ Fe-2343
m4p™ Fe-2343 is a metal powder categorized as tool steel due to its chemical composition. During the powder manufacturing process, special measures are taken to enable the additive processability of this high-carbon tool steel using conventional equipment (as-built platform temperatures below 200°C). The powder is atomized with argon and specifically adjusted to achieve high purity and an optimal grain shape for the process.
Martensitic hardening results in high hardness values of approximately 48 HRC in the as-built state, which already corresponds to a hardened state. The hardening can be regulated by repeated tempering, increasing the hardness to 52-56 HRC using a secondary hardness maximum.
m4p™ Fe-2343 is used in various tool manufacturing and mold construction applications. Its good toughness properties, high heat resistance, and good thermal conductivity make it suitable for injection molding and die casting, as well as general tools, knives, or extrusion dies. For the production of large-volume components, a hybrid build approach is recommended.
